Abstract
INTRODUCTION: Seizures count to critical situations emergency medical systems (EMS) are confronted with. OBJECTIVES: Evaluation of a modified treatment algorithm (MTAS-EMS) using diazepam and midazolam due to a supply bottleneck of iv lorazepam in 2012. METHODS: Retrospective study where data from patients treated for seizures by the EMS of the city of Zurich were analyzed. Effectiveness of the MTAS-EMS and i.v. diazepam in children and adults was compared with respect of cessation of seizure without recurrence over the period until arrival at the hospital. The chi-square and Fisher's exact test were used to compare categorical data. The Student's t-test and Mann Whitney test were used to compare numerical data. p-values < 0.05 are considered significant. RESULTS: Of 584 documented missions, 165 treated patients (126 adults and 39 children) were included. 115 patients (80 adults and 35 children) were treated according the MTAS-EMS. Cessation of seizure was achieved in 85% of the adults and in 97% of the children, if all options of the MTAS-EMS were used. The first dose of nasal midazolam was more successful in children compared to adults (p = 0.012). In adults, the single dose of i.v. diazepam terminated the seizure in 98% (p = 0.001) compared to 57% for the single dose of iv and 64% for nasal midazolam. CONCLUSIONS: The treatment success of the MTAS-EMS is high. However, in adults the single dose of i.v. diazepam is as successful as the completely used MTAS-EMS and seems to be superior to the single dose iv and nasal midazolam.
